Five 2-liter soda
bottles with slits on the side "hoot" in the wind. The bottles are
mounted on a strip of wood at the cap end. This will allow the
bottle to be turned with the wind blowing perpendicular along the slit.
The bottles
emit a haunting sound as the wind blows. The pitch will rise the
harder the wind blows. In the middle of the video, my outdoor motion
sensing light will go out for a while, making that portion dark.
